Nothing worse than substituting Jesus with self-righteousness

From a recent FB status update by John Fonville: “As destructive and defiling sexual sin is to the individual and church-and it is!- moralistic idolaters in the church are ultimately far more destructive and Christ-denying because they erect all manner of extra-biblical requirements for holiness that God’s law doesn’t forbid or require! And they substitute Christ and His righteousness for a Christ-denying, self-righteousness. Thus, they shift the ground of justification from Christ to self. Paul begins 1 Corinthians by addressing the Corinthians as “saints” (1:2). But he begins his letter to the Galatians by calling them cosmic traitors and pronouncing a curse of final judgment on any who proclaim or receive a different gospel (Gal. 1:6-9).”
